yever feel like you have nothing in common with any of your friends? like they're all cool and we like each other and stuff but i feel like we don't have anything to bond with because we don't like any of the same things

In my experience, my friends like to listen to me talk about the things I like, even if they wouldn't want to do those things themselves. I'm not trying to say that your friends are definitely like that, too, but it's possible that you have something to bond over just by liking something at all.

yeah i guess its just that like, everything i like is from like 20 or 30 years ago and all my friends are younger than me so naturally they wouldn't be interested, and the people who do like those things are like in their forties and probably not that fun to be around
